Thought I'd share a component/s I've used for quite a while to help layout water if you use the TS water in the mold package. It's just a couple of different adjustable 3d wire shapes used to create water. I've used these for years just to put in water more easily on standard circuit shapes I use. That way you can easily adjust location and depth by using the Modify Component (in single mode). Just put the folder in your LIB3D folder.

May give you some ideas on how to do some things when TS7.8 with mold is released.

They are AS IS, and use at your own risk! Tear them apart and modify to your hearts content. There is 5 different circuits.
